ATAVRSB202

The ATAVRSB202 smart battery board is an evaluation and development kit for the new AVR Smart Battery device, the ATmega32HVB. This device is made for battery packs with two, three, or four lithium ion and lithium polymer cells in series, and feature autonomous battery protection as well as very accurate voltage, current, and temperature monitoring capabilities. The device provides the means to protect the battery pack and surroundings from hazardous conditions and gain the most from the batteries. The SB202 targets smart batteries with two, three, or four lithium ion and lithium polymer cells in series. The product is based on the same firmware source code, but compiled differently for each configuration. The SB202 board consists of three parts: the edge connector, the main area, and the connector and support area. The main area contains all the circuitry needed in a battery pack design.

• ATmega32HVB Smart Battery device evaluation and development kit
• High side N-FETs
• 5m ohm sense resistor current measurements with 18bit CC-ADC
• Input filters for cell voltages to the 12bit voltage ADC
• All components on one side
• Polarity safety FET
• Holes for mounting of pin headers or wires
• ISP connector for programming via SPI, and debugging via debugWIRE interface
